Active Directory Account Lockout - Narrowing Down the source

If you are in a all-windows shop where everything is nice and neat, everybody has a proper domain membership and all authentication is SSO or Windows Integrated, then you probably do not have much of a problem with repeated account lockouts. On the other hand, if you are in a mixed environment, lots of :Linux, Mac, and unmanaged Wintendo, then you probably run into some users that manage to Lock themselves out frequently - typically for several days in a row after the account password had been changed. Reasons can be plenty fold - typically saved credentials somewhere, like a git client, sql-server client, email client, rdp-manager, smbfs-automount, or anything that tries a bunch of logins when you start it up, or keeps trying in the background. As a sysadmin, you don't have time to narrow it down for the end user - but they will be adamant it is not their fault, so you probably need to prove that "Yes it is" - so I use powershell to grab 4740 events from Domain Con...

Campground Networking

I've travelled a couple years full time in an RV, working remotely. This can be a challenger, many campgrounds have poor Wi-Fi setups, and cell service is not always great (Do not plan on doing any work from the Grand Canyon National Park). Calling ahead and asking usually does not reveal accurate information, you are best off using campground reviews, search them for WIFI and read what people say.  The best network I have seen was at Eagles Landing RV Park in Holt, FL (Pan handle) http://eagleslandingrvpark.com/. Still not perfect. At poor sites, more than once did I offer my assistance in trying to configure and improve, but even the places which have no vendor maintain their system do not want any other hands on it. A couple of times I helped out anyway, default passwords on routers, so I upgraded their firmware, disabled 802.11b, and set a password so no-one else would mess with it. My RV network setup is not of a common type, you sort of have to be a bit of a network-guy to us...

Cisco UCS Mini - Add Extender Chassis

If you happen to own a UCS Mini Setup, a 5108 Chassis with two Fi 6324 or similar, and you are looking for documentation on how to add another 5108 Chassis with fabric extenders (2204XP in my case), then Cisco really does not have much out there, nor is there a lot of googlable information either (Everything you find is related to standalone Fabric Interconnects and "standard" UCS). Even after calling TAC, it took a while to get something, and what they told us was not even accurate. So here is how we did it, and it worked, came up without any interruption to current chassis, network, or running profiles. Equipment Of course we used our Cisco vendor to spec the equipment, but just for reference here is the list of what we had and what we added: Original Setup 5108 Chassis  Fi 6324 (Qty 2) Ports 1-2 for Fibre Channel, and 3-4 for Ethernet (MMF) Connected to a stack of switches and pair of FC switches/SAN Running UCS version 4.0.1 (Fairly recently upgraded as of M...
